[Limdep Nlogit List] model that could?

[Durham, Cathy]

If you have variation in the partial adoptions you can simply use a
Probit or logit model in Limdep. In some software they round the
non-zero and one values up or down but not in Limdep. Thus your share of
adoption becomes the dependent variable and the marginal effects
produced can be interpreted as changes in the share of adoption. There
are a few analysts who have used this approach to examine share
variables, and that is what Probit was originally designed for. I've
discussed this in a paper where I used it for a share dependent variable
and cite some of the relevant literature, and discuss the model tests.

Hi
Could you please tell me whether Tobit model would applicable in the
following case or some other options will better suit?
 
A given technology has been adopted fully by some individuals; to some
extent by some individuals, and not at all by some. (example, a new
clone of a crop grown in entire land area available in some case (1) ;
part of the available land in some cases (0.7) and not at all (0) but
still practice the old crop in some cases). Thanking you in advance
 
 
Kind Regards
 
Upananda
